Every evening around school dismissal time, if you look toward the west, you'll find the sunset sky often turns a fiery red, and Grandpa Sun looks like a big red apple—so beautiful! Why does this happen? Little Panda is here to reveal this magical color trick: At dusk, as the Sun goes down, sunlight has to travel sideways through a layer of atmosphere that is much thicker than during the day. Playful blue light gets bumped around and scattered away halfway by the thick air, leaving only the strongest red and orange light to push through the air barrier and reach our eyes. So, beautiful glowing sunsets are actually the result of light playing a 'bending game' in the atmosphere!
